Synopsis

Improper validation of Bluetooth device names can lead to arbitrary
command execution.
Background
==========
bluez-utils are the utilities for use with the BlueZ implementation of
the Bluetooth wireless standards for Linux.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

Description
===========
The name of a Bluetooth device is improperly validated by the hcid
utility when a remote device attempts to pair itself with a computer.
Impact

resulting in arbitrary commands being executed as root upon attempting
to pair the device with the computer.
Workaround
==========
There are no known workarounds at this time.
